Sleep is disturbed in critically ill patients and is a frequently overlooked complication. The aim of our study is to evaluate the impact of sound levels in our surgical ICU on our patients' sleep on the first night of admission. The study was performed in a tertiary care university hospital, in a 12-bed surgical ICU. Over a 6-week period, a total of 148 adult, non-intubated and non-sedated patients completed the study. During this six-week period, sound levels were continuously measured using a type II sound level meter. Sleep quality was evaluated using the Richards-Campbell Sleep Questionnaire (RCSQ), which was completed both by patients and nurses on the first morning after admission. A non-significant correlation was found between night sound levels and sleep quality in the overall sample (r = -1.83, 95% CI; -4.54 to 0.88, = 0.19). After multivariable analysis, a correlation was found between higher sound levels at night and lower RCSQ evaluations (r = -3.92, 95% CI; -7.57 to -0.27, = 0.04). We found a significant correlation between lower sound levels at night and a better quality of sleep in our patients; for each 1 dBA increase in LAFeq sound levels at night, patients scored 3.92 points lower on the sleep questionnaire.
重症患者的睡眠会受到干扰，这是一种经常被忽视的并发症。我们研究的目的是评估外科重症监护病房（ICU）的声音水平对患者入院第一晚睡眠的影响。该研究在一家三级护理大学医院的12张床位的外科ICU中进行。在为期6周的时间里，共有148名成年、未插管且未使用镇静剂的患者完成了研究。在这六周期间，使用II型声级计持续测量声音水平。使用理查兹 - 坎贝尔睡眠问卷（RCSQ）评估睡眠质量，患者和护士在入院后的第一个早晨均完成该问卷。在总体样本中，夜间声音水平与睡眠质量之间未发现显著相关性（r = -1.83，95%置信区间；-4.54至0.88，P = 0.19）。经过多变量分析，发现夜间较高的声音水平与较低的RCSQ评估之间存在相关性（r = -3.92，95%置信区间；-7.57至-0.27，P = 0.04）。我们发现夜间较低的声音水平与患者较好的睡眠质量之间存在显著相关性；夜间等效连续A声级（LAFeq）每增加1分贝，患者在睡眠问卷上的得分就会降低3.92分。
